MACHINE FOR CLEANING COTTON.

SPECIFICATION forming part of Letters Patent No. 437,303, dated September 30, 1890.

Application filed March 8, 1890. Serial No. 343,126. (No model.)

.To all whom t may concern:

Be it known that I, GUSTAV JOSEPHY, a subject of the Emperor of Austria-Hungary, residing at Bielitz, Austria-Hungary, have invented an Improved Machine for Cleaning 1(.Jlotton, of which the following is a specifica- This invention relatesto a machine for removing the impurities from cotton preparatory to carding and from cotton waste.

It has for its object to so construct the machine that the cotton is cleaned without the use of any air-blowing device whatever, which is objectionable.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure lis a vertical longitudinal section of my im-v proved machine for cleaning cotton, showing it provided with five adjustable scutcherknives and five xed doier-knives. Fig. 2 is a sectional side view of part of the machine, showing seven scutcher-knives and their adjusting mechanism. Fig. 3 is an end View of Fig. 2 with screw-rod z2 removed. Fig. 4 is a detail side view of the hand-wheel e and screw threaded rod, hereinafter described; and Fig. 5 is a sectional side view of part ot the machine, showing both the scutcherknives and denier-knives adjustable. In this gure seven scutcher-knives and six dofferknives are shown.

The charge passes from the feed-cloth a under a safety-roller a and thence between a pair of feed-rollers b b. From rollers b b the charge passes between roller c and feed-bars c to the first scutcher d, having a toothedwire working-face. The scutcher spreads the cotton into a thinv bat and forces it against the knives placed opposite the scutcher. Each of these knives e20 @26, Figs. 2 and 5, is bolted to a pair of arms e e e e e? e2, &c., Fig. 3, pivoted at their inner ends by gudgeons s s, 660., .to a fixed plate A, while at their free ends they carry the studs @10 e11 cl2, &c.

Two pairs of arms-viz., e52 and e3, Figs. 2 and 5, and e and e2, Fig. l-are at their free ends connected to a pair of triangular plates fw by means of their studs. The other arms are in turn connected at their free ends to the platecarrying arms by means of links t t4 encircling their studs, as shown. It will be seen that by imparting motion to the plate w the arms c e will be vibrated, and thus the distance between the cu tting-edges of the knives and the scutcher will be altered.

The plates w are connected to a shaft w, Fig. 3, embraced bya screw-shaft z2, entering a tapped hub on ahand-wheel z. By revolving the hand-wheel the shaft z2 will be moved backward or forward, taking the shaft fw with it, and thus moving the plates fw to oscillate arms c e6, as described.

By means of the knives e2@ e2 the solid impurities-such as scales and grains-are beaten out of the cotton held to the scutcher, the latter revolving at a speed of about eight hundred revolutions per minute. The impurities removed by the knives e2() e26 fall into a receptacle f. From the first scutcher d the purifled charge passes by the doifer g to a second scutcher h. The doffer g has a working-face much finer than the scutcher d.

Opposite to the dofter knives are placed, as shown. These knives may be either fixed, Fig. 1, or adjustable, Fig. 5. If adjustable, the doffer-knives 112 are bolted to arms @15, pivoted to fixed plate A and having studs 10 @15 on their free ends, encircled by linksr r3. The arms il 5 are oscillated on their pivots/v o5 by means of the plate u, shaft u, screwshatt x2, and tapped hand-wheel the same as already described in relation to the knives @20 @26. By the knives @"2O t'25 the impurities which may still remain in the material are beaten out of it and fall into the compartment lc.

The bat passes from the doer to the second scutcher h, having a very fine and compact coating of toothed wire and rotating at about twelve hundred revolutions per minute. Here the cotton, which has but slightly penetratedthe coating of the drum d and g, is somewhat carded and is at the same time reversed. A

backing-off roller Z, rotating with a very high speed, beats the cotton again, so that the impurities, if any, are removed and thrown out of the machine. A stripping-knife m, placed between the scutchers CZ h, prevents the cotton from being taken up by scutcher d from scutcher h.

A cylinder n is placed behind scutcher 7L and is furnished with strong radial leather strips. By this cylinder the bat is loosened from scutcher h and is thrown forcibly against the delivery-rollers o p. All impurities which may still be retained will be blown out in dust form and will fall through a screen r, surrounding rollers /rL and z, into the compartment k.

The advantages of this machine are, among others, that the cotton is subjected to a continual process of carding and beating', while the passage of the material through the ma chine and its delivery are performed entirely Without a blast other than that generated by the parts described.

1.The combination, in a cotton-cleaning machine,of the seutehers d 7L and doilfer g with a series of knives operating against seuteher d, substantially as specified.

2. The combination of feeding devices with scutchers (l h, doiler g, knives operating against the rollers (l g, and with the take-oit roller Z, operating against roller h, and with the discharge-roller n and screen r, substantially as specified.

The combination of seutchcr (Z with pivoted arms, knives secured thereto and operating against the soutcher, links t t", conneeting the arms, and with plates w', shaft w, screw-shaft z2, and tapped hand-wheel z', for vibratin g the arms, substantially as specified.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnesses, this 8th day of February, 1890.

GUSTAV JOSEPIIY.
